I3 Venture awards info

Emory is full of fledgling biomedical proto-companies. Some of them are actual corporations with employees, while others are ideas that need a push to get them to that point. Along with the companies highlighted by the Emory Biotech Consulting Club, Dean Sukhatme’s recent announcement of five I3 Venture research awards gives more examples of early stage research projects with commercial potential. This is the third round of the I3 awards; the first two were Wow! Read more

Take heart, Goldilocks -- and get more sleep

Sleeping too little or too much increases the risk of cardiovascular events and death in those with coronary artery disease, according to a new paper from Emory Clinical Cardiovascular Research Institute. Others have observed a similar U-shaped risk curve in the general population, with respect to sleep duration. The new study, published in American Journal of Cardiology, extends the finding to people who were being evaluated for coronary artery disease. Arshed Quyyumi, MD and colleagues analyzed Read more

Beyond the usual suspects among Alzheimer’s proteins

If you’ve been paying attention to Alzheimer’s disease research, you’ve probably read a lot about beta-amyloid. It’s a toxic protein fragment that dominates the plaques that appear in the brains of people with Alzheimer’s. Many experimental therapies for Alzheimer’s target beta-amyloid, but so far, they’ve not proven effective.

That could be for several reasons. Maybe those treatments started too late to make a difference. But an increasing number of Alzheimer’s researchers are starting to reconsider the field’s emphasis on amyloid. Nature News has a feature this week explaining how the spotlight is shifting to the protein ApoE, encoded by the gene whose variation is responsible for the top genetic risk factor for Alzheimer’s.

In line with this trend, Emory’s Alzheimer’s Disease Research Center recently received a five-year, $7.2 million grant to go beyond the usual suspects like beta-amyloid. Emory will lead several universities in a project to comprehensively examine proteins altered in Alzheimer’s. You’ve heard of the Cancer Genome Atlas? Think of this as the Alzheimer’s Proteome Atlas, potentially addressing the same kind of questions about which changes are the drivers and which are the passengers.

Emory’s back-to-basics proteomics approach has already yielded some scientific fruit, uncovering changes in proteins involved in RNA splicing and processing. Also, the Nature feature also has some background on a clinical trial called TOMMORROW, which Emory’s ADRC is participating in.

Two heavy hitters in this week’s Nature

Two feature articles in Nature this week on work by Emory scientists.

One is from Virginia Hughes (Phenomena/SFARI/MATTER), delving into Kerry Ressler’s and Brian Dias’ surprising discovery in mice that sensitivity to a smell can be inherited, apparently epigenetically. Coincidentally, Ressler will be giving next week’s Dean’s Distinguished Faculty lecture (March 12, 5:30 pm at the School of Medicine).

Another is from Seattle global health writer Tom Paulson, on immunologist Bali Pulendran and using systems biology to unlock new insights into vaccine design.
